New profile each time when user logs in

More precisely the database call which is checking if a profile type exists, returns zero always for me.
I made a PHP page with this code:

<?php
global $user;
$account = $user;
$profile_types = array_keys(content_profile_get_types('names'));
$result = db_result(call_user_func_array('db_query', array("SELECT COUNT(*) FROM {node} WHERE uid = %d AND type IN (". db_placeholders($profile_types, 'text') . ")", $account->uid) + $profile_types));
print ($result);
?>

And I get 0 as result with admin and test user.

I changed the if-statement to this:

<?php
$arguments[] = $account->uid;
$arguments = array_merge((array)$arguments, (array)$profile_types);
if (db_result(db_query("SELECT COUNT(*) FROM {node} WHERE uid = %d AND type IN (". db_placeholders($profile_types, 'text') . ")", $arguments)) > 0) {
    return;
}
?>

and now the user won't get a new profile on each login. This is easy to patch if it looks ok.

The problem with my own solution above is that it won't update the profile if user already has a profile. So it can be used only when user registers for an account for the first time. But I really need to update the profiles when user logs in. So I changed the code to work if user has one profile. I have no idea what to do if user has many profiles in the site, which is quite unlikely in my opinion.

Anyway, here is the changed code (replacing if-statement on line 322 in openid_cp_field.module)

<?php
$node = new StdClass();
$node->type = $type;
if ($node->nid = content_profile_profile_exists($node, $account->uid)) {
  $profile = node_load($node->nid);
} else {
  $profile = new StdClass();
}
?>

This way the user's profile (only the OpenID AX mapped fields) is updated on the RP site each time user logs in.
